"I get it now"
*just as {mystic insight} describes, this monster's made out of living creatures' shadows, meaning it cannot be hit, while its skill {shadow manipulation} creates physical items out of non-living beings' shadows.
If my guess is right..
Then that javelin in his hand has a physical presence, and can be hit by my spells, meaning it can also hurt me*
'Let's test this'
Hans displayed both his palms in the direction of the monster, and cast the spell { blizzard}.
A freezing cold aura emanated from his hands, even colder than the ones he had cast before.
A second later, a thick layer of ice created on the desert's surface, making it all slippery and solid.
Even then, the monster's feet just passed through it, posing on the original sand, and only one thing was completely frozen by Hans's wide spell.
In the hand of the shadow, the javelin became more similar to an ice spike than anything else.
